3.Using Method

3.1TCP/IP connection

When XZ-DG4 works in the TCP/IP connection mode, data communication between XZ-DG4 and server is fully transparent transmission, to keep XZ-DG4 always online, users need to define the registered data frame and heartbeat data frame, and the server needs to differentiate the registered data frame and heartbeat data frame from user data frame. The server can also remotely set XZ-DG4's SDN or domain name.

3.2 Server Remote Setting Parameters

When the DTU is connected to the server, the DTU can perform IP read/set/delete functions through the server.

3.3 SMS function use        

When XZ-DG4 works in SMS mode, XZ-DG4 can communicate with any mobile phone by SMS. When the mobile phone sends any message to XZ-DG4, XZ-DG4 from serial port sends out the current SMS content (only support up to 70 ASCII characters), if the terminal equipment returns data from serial port (only a maximum of 70 ASCII characters) XZ-DG4 will automatically reply the data to the mobile phone number from which it receives text messages last time.          

Special customization requirements for SMS function is supported
